. To all whom it may concern:

and State of Texas, have invented certain new and useful Improvements inRoad-Surfacin Machines, of which the following is a speci cation.

This invention relates to new and useful improvements in a roadsurfacing machine. The object of the invention is to provide a machineof the character described which is specially designed for applying asurface of concrete or other similar material to roads and streets, andincludes means for spreading the surfacing material over the foundationof the roadway as well as means for tamping said material, so as to givea true and even surface.

A further feature of the invention resides in the provision of a machineof the character described provided with means for smoothing and givinga finished appearance to the edge of the roadway. A still furtherfeature of the invention resides 1n the provision of a flexible apron,whichfollows the tampers and imparts a roughened surface to the finishedroadway, so that the concrete or other surfacing material will notharden into a perfectly smooth and slippery surface. With the above andother features in view the invention has particular relation to certainnovel features of construction, operation and arrangement of parts, oneexample of which is given in this specification and illustrated in theaccompanying drawings, wherein:

Figures 1 and 2 show, respectively, a plan view and a front elevation ofthe device.

bottom. views, respectively, of the track braces.

Referrin now more particularly to the drawings w ereinlike numerals ofreference designate similar parts in each of the figures, the numerals1, 1 refer to the end castings of the framework, the op osite ends ofeach of which are formed int the legs 2, 2. The free end of these legsare formed into alined bearings wherein the shafts 4: and 4:

respectively, rotate, and, mounted on these shafts are the supportingwheels 5 and 5,

formed to move upon the track 6. The end castings are connected by theside members 7 and 8 preferably formed of channel irons, which, togetherwith the end I-beams 9, 9 form the frame-work of the machine.

Mounted upon this framework is a suitable motor 10 having thedrive-shaft 11.

Fixed upon one end of this shaft is a friction-wheel 12, and upon theother end thereof is the screw-gear 13. Fixed upon the front side of theframe-work are the bearings 14k, 1 1 in which the shaft 15 rotates.Splined upon this shaft is. the friction-wheel 16 which may be broughtinto and out of contact with the friction-wheel 12 through the eccentricbushing, shown in detail in the instrumen- The frictionwhe'el 1-6 may beshifted toward and from thef'center of the'friction-wheel 12, so as todecrease or increase' the speed of rotation thereof, and may be shiftedfrom one side to the other of said friction-wheel 12 so as to reversethe rotation of said wheel 16, this shifting being accomplished throughthe instrumentality of thehand-lever 18. A. long counter-shaft 19 ismounted in suitable bearings carried by the respective castings 1, l andis also provided with a central bearing 20 carried by the side member 7.Fixed upon the shaft 15 is a sprocket-wheel 21 and in alin'ementtherewith is the sprocketwheel 22 which is fixed upon the shaft 19, andoperating over said sprocket-wheels and transmitting rotation from. theformer to the latter, is the sprocket-chain- 23. The legs 2, 2, have thealined bearings 24, 24L- wherein rotate the short shafts 25,25. Fixedupon the respective ends of the counter-shaft 19 are the smallsprocket-wheels 26, 26, in alinement with the large sprocket-wheels 27,27 which are fixed upon the shaft 25, and operating over thesesprocket-wheels and transmitting rotation from the former to the latterare the sprocket-chains 28, 28. I Each shaft 25 has a smallsprocket-wheel29 fixed thereon and in alinement with a largesprocket-wheel 30 which is fixed upon -t e corresponding shaft 4 andoperating over these splroocket-wheels and transmitting raj-- tationsprocket-chain 31. A

It is obvious that the traction mechanism hereinbefore described may beoperatively connected with and disconnected froin the motor 10 bybringing the friction-wheel 16 into or out of mesh with the frictionwheel 12 through the instrumentalityof the hand lever 17 'It is furtherobvious that 'the speed thereof may be varied and the movement'reversedby shifting said frictiomwheelld back and forth on its shaft 15, throughthe instrumentality of the hand-lever -lfi'.

The screw-gear 13 is in mesh with a screw-gea'r32 which is fixedonshaft'33, this shaft is rotatable in suitable and has the small sprocketwheelSi lfixed thereon and in alinement with a larger sprocketwheel which ison the shaft 36, A sprocket-chain 37 operates over these srocket-wheels'and transmits rotation from t e former to the latter.-Loosely. mounted on the shaft36 are'the sprocket-wheels 38 and 39, whichare spaced apart and splined on the shaft 36; "between saidsprocketwhoels 38 and 39 is a double clutch. inember 40 which j ismanipulated back and forth s we et-wheel 39 through the sprocketc ain49.

through the hand-lever 41 in the, Well known manner. vThe inner sides ofthe sprocket wheels 38 and 39 are formed into the respective clutchmembers 42 endsa with which the clutch member O'may be alternativelyengaged so as to force the sprocket-wheels 38 and 39 to rotate; with theshaft 36. Two

counter-shafts 44: and '45 are mounted in suitablebearings carried b theframe-work, the former of which has t e sprocket-wheel whee147inalinement with the sprocketwheel'39. The sprocket-wheel 46, fixed onthe shaft 44 is driven from thesprocket wheel 38 through thesprocket-chain 48, and

the s rocket-wheel 47 f-is driven from the Extending "the full width ofthe machine is a spreader 50 which is formed of a metallic plate, orrunner, whose front edge is turned up at right angles to the roadsurface. a This spreader is supported by :a plurality of supporting rods51, to the lower ends of. which the spreader is secured, the upper endsof said rods being hinged to the frame-work at the point 52 and the rodsbeing provided with turn-buckles 53 to permit the vertical adjustment ofthe spreader. A plurality 'of' connecting rods 54ers pivoted at theirfor-v ward ends to the spreader and whose other in the formerto thelatter is the which is'a transverse metallic plate whose edges areup-turned, as shown in Fig. 3-.

' This plate extends the full width of the mlachine and both thespreader 50 and temper 57 are curved, as shown in Fig. 2 to con cm tothe desired curvature of the surface ofthe roadway bein formed. I

to, 'anddepen ng from, the side of f the framework are the vertical 7bearings 58 through which the tamper-rods 59 operate. The upperendsofthese rods haveeccentric bea 60 on the shaft 44 and as said shaftrotates said rods 59 are reciprocated-vertically, Each of the rods 9isprovided with a'turn-buckle' 61 for adustment and the tamperjissupported by said rods, being connected to thelower endsthereof-ithrough a yieldable connection shown indetailinFl Y Shown in 8is simmer 62 which is formed of: a curved metallic plate and is providedto smooth and I give a uniform curved contour tothe edges of the roadsurface." ,The "frontjand rear ends of this runner are upwardly curved,as at 63 and 64. vDepend ngfrom'itheres ective end castings 1,1 are thebearing-p ates 65, 65 each having a vertical'slot 66, and the run ner 62has an upstanding flange 67, integral through the slots 66.,andarethreaded into the flange 67. These bolts secure, the runners 62 m"positionand permit'the vertical adjustment relative :to the bearings65.

Inthe formation of a road surfaceth'e concrete or' other surfacingmaterial is poured onto the road foundation in front of the machine; Asthe machine .moves forrial and smooths-them down and spreads the-material uniformly over the 1 roadway. When this is done theclutchqnember 40 is it will be slippery. For the purpose of imarting arough surface to the finished road have provided a transverse apron 69therewith. Suitable securing bolts 68 pass ward the oscillatingspreader'50 first comes 1 in contact wlththe piles of surfacing matefreeportion rests uponthe surface being i mosses formed of heavy coarsefabric or some similar material. The upper edge of this apron is securedto the transverse beam Whose ends are anchored to the rear legs of theend castings 1, 1. This apron extends the full width of the roadway andits lower edge is free and drags over the smooth surface and slightlyrou hens the same so that when surfacing it wil have a uniform ovalcontourbut will not, when hardened be slipper hat I claim is:
